SAFETY DEVICE FOR- VEHICLE-TONGUES.

Application filed March 10, 1915. Serial No. 13,529.

0 all whom it may concern:

Be it known that I, JorrANN KRIsTJAN- SON, a resident of Mozart, county of Humboldt, Province of Saskatchewan, in the Dominion of Canada, have invented certain new and useful Improvements in Safety- Devices for Vehicle-Tongues, described in the following specification and illustrated in the accompanying drawings, that form part of the specification.

The principal objects of the invention are, to prevent the fouling of the lines under the end of the tongue, and to prevent the neck yoke from being accidentally withdrawn from the tongue.

The principal feature of the invention consists in the arrangement of a guard member secured to the underside of the tongue at the forward end whereby the neck yoke is locked in place and a sloping bar is presented to guide the lines free.

In the drawings, Figure 1 is a side elevational view of the forward end of a wagon tongue showing my invention applied there to and illustrating the manner in which the Fig. 2 is a side elevational view showing the locking member open and the neck yoke removed.

Like numerals of reference indicate cor responding parts in each figure.

Referring to the drawings, 1 is the tongue having the usual tip iron 2 secured to its extremity, said iron having the downwardly projecting member 3 arranged midway of its length on the underside against which the ring 4 of the neck yoke 5 engages in backing up the vehicle to which the pole is attached.

It is a very frequent occurrence for team-. sters to get their lines caught under the end of the tongue projecting beyond the neck yoke and when such a thing occurs, it becomes a diflicult and often times dangerous matter to release the lines, and further it is a common occurrence for the neck yoke ring to be withdrawn from the tongue if the horse be loosely coupled to the whifiletree. This is very dangerous as it leaves the tongue of the wagon free to swing though the horse may still move ahead. In order to eliminate both of these dangers and inconven iences, I provide a protecting member 6 formed of a length of rod and preferably of spring material. The end 7 of the member 6 is rigidly secured to the underside of the tongue to the rear of the tip iron 2 and the portion 3 of the tip iron.

is bent in a forward and downward direc- Mon at a point considerably to the rear of From the extremity of the downwardly bent portion'8 the bar extends forwardly and upwardly in a gentle curve to meet the tip iron at a point close to its forward looped extremity. The loop 1s then returned along the underside of the tip iron and bent downwardly and forwardly at its extremity forming the point 9 which engages the underside of the tip iron close to the downwardly extending portion 3. The neck yoke ring a is then prevented from slipping forwardly as it Wlll engage the point 9 and pull against the member 6 but it cannot get away.

In order to obviate any undue strain upon the curved underside forming the guard, I preferably provide a tie bolt 10 extending between the downwardly turned portion 8 and the approximately parallel portion extending from the point 9.

The member 6 being of spring material is retained in close contact with the underside of the tongue at all times but it may of course be sprung downwardly in order to release the neck ring and to allow the placing and removal of same upon the tongue. In order to facilitate the placing or removal of the neck yoke I provide a lever 12 pivotally secured upon the bolt 13 extending through the tongue. This lever is of a fork shape and carries a bolt 14 extending across the lower end upon which is arranged a roller which engages the portion 7 of the member 6 and springs the said member outwardly. This lever is so arranged that it will hold the member open while the neck yoke is being placed or removed from the tongue.

The curved underside of the guard 6 ex tends rearwardly to a point back or beneath the neck yoke 5 so that if the lines forward of the neck yoke should loop over the end of the tongue the looped portion cannot possibly get back of the inward extremity of the curved underside of the guard member 6 and this guard member is arranged at such an angle of inclination that upon a teamster pulling upon the lines, they will slide freely in an upward and forward direction and clear the end of the tongue and the danger incident to a horse becoming frightened through the efforts of a teamster endeavoring to get his lines loose is thus obviated and in addition the neck yoke is locked se rcurely against accidental removal. The deunderside of the tongue and having a forwardlyand upwardly sloping guard eXtends ing'to the end of the tongue and formed With a stop member arranged intermediate of its length adapted to retain the neck yoke ring from accidental removal, and 2 lever pivotally supported from the tongue and adapted to depress said spring member to release the neck yoke ring.

Signed at the village of Elfros in the 15 Prov. of Sask. this thirteenth day of J anuary 1915.
